A so in t 1e machine of ap licants prior patent adjustments can be ma e for operation upon but two portions of the sole, and in the machine of the Gifford patent adjustments can be made for operation upon but three portions of the sole.

I The objects of the present invention are to rious parts of sole leveling machines of the class to which the present invention relates.

With these objects in view the present invention contemplates the provision in a sole leveling machine com rising a sole leveling roll, or other suitable eveling device, ashoesu porting jack, and means to chan e-the iel ative lateral'inclination of theroIl and jack, of means for independently adjusting the lateral inclination of the roll and jack for operation upon any one of a lurality of different ortions of the shoe. The adjustment of the lhteral inclination of the roll and jack for operation upon each portion ofthe shoe can thus be made without affectin the lateral inclination of the roll and jacfi while a different portion of the shoe is being operated upon, and buta single adjustment isrequired to cause the roll to act in the desired manner atany portion of the shoe.

In the preferred form of the invention mechanism is rovided, as in the machines of the patents liereinbefore referred to, for changing the relative lateral inclination of the roll and jack, which mechanism is 'provided with an adjusting device, and the independent adjustment of the lateral inclination of the roll and jack for operation u on different portions of the shoe is produced by meansof a plurality of mechanlsms eaclr of which is rovided with means of adjustment and whic are arranged to actuate'said adjusting device'independently at different times during the leveling operation. This .times during the means for securing an independent adjustment of the relative lateral inclination of the roll and jack for operation upon different portions of the shoe provides a simple,- effic'i'en't 'and' compact construction not only for changing'the adjustment of the lateral inclinati mof the roll and jack, but also for of n-g'ing the relative lateral inclinationof the roll and jack as the different 'portions of thes'ole are acted upon successively .by'. the

roll} This construction ies-believed to, be new, and a feature of the inventionisconsidered to consist in the provision 'ina sole levelwjing machine provided with mechanism for relatively actuating the roll and jack to level the sole of a shoe of.aplurality of mechanisms which act independently at different adjust the mechanism for ing the roll and jack.

In the best form of the invention which has as yet been devised, the mechanisms for actuating the adjusting device above referred relatively actuatto consist of a series of cam plates each of which is operatively connected with an actuatin-g cam by which it is moved at the proper time durim the o eration of the machine to act, through suitalile connections, on the adjusting device, the said actuating cams being so arranged that the cam plates are brought into operation successively so that each cam plate in turn controls the position of the adusting device.

In addition to the features of invention above referred to the present invention also consists in certain devices, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be. obvious to thoseskilled in the art from the following description.

The various features of the present invention will be clearly understood from an illspection of theaccompanying drawings in which v Figure 1 is a view in side elevation of a vibrating roll sole leveling machine embodying the same in their is a view in rear end e evation of the machine illustrated in Fig. 1, with certain artswhich Would appear in said view omitte 'Fig. 3 is a detail view in side'elevation illustrating the construction and arrangement of the mechanisms which act'success ively during the operation of themachine to move the adjusting device of the mechanism for changing the relative lateral inclination of the jack and roll, and Fig. 4 'is a detail'plan view of the -mechanism'1llustrated in Fig. 3.

operation of the machine to referred form. Fig. 2

' 11 Except for the mechanism which constitutes the -illustrated embod-iment of the present invention the machine illustrated in igs. 1 and 2 is substantially the same in construction and mode of operation as the machinedisclosed in applicants prior patent N 0. 555,548, comprising two zshoe supporting jacks, two vibrating sole leveling rolls cooperating respectively therewith, mechanism for actuating the jacks to change the relative longitudinal position of the jacks and rolls, means for-connecting and disconnecting each 1 jack and the jack oscillating mechanism, and means for tipping'the rolls} to change-the re1a-' tive lateral inclination of a .jack and ts cooperating roll during the leveling OIiIEIiLtIOII."

The jacksare indicated at '1 int e position which they assume when disconnected from the jack oscillating mechanism, and-are pivotally mounted at 2 in the front portion of otally mounted at 8 1n the up )er rear or' tion of the machine frame. ach leve ing roll is vibrated by means of an eccentric 9 on a constantly rotating shaft 10 journaled in the upper rear portion of the machine frame, which eccentric acts upon a rod 11 extending through the sleeve to which the roll carrier 6 is secured, and provided at its forward end with a light yoke 12 engaging the shaft of the roll 5. The mechanism-for tipping the rolls during the leveling operation to change the relative lateral inclination of a jack and its cooperating roll is arranged to act upon the roll carriers 6. This mechanism com rises a cam groove 13 in one face of the cam isk 3, a lever 14 provided with a roll or stud engaging the cam roove, a bell. crank 15, a link 16 connecting the free end of the lever M and the horto be'varied the link 17 is ad'ustably con izontal arm of the bell crank 15, a-lin'k 17 connected at one end to the vertical arm of the bell crank 15, and connections between the other end of the link 17 and the roll carriers 6,

these connections as Well as the parts hereinbefore referred toand all other parts appearing on the drawings and not hereinafter specifically referred to being constructed and arranged to o. erate in the same manner as the correspon ing parts of the machine of applicants prior patent No.555,548.

During the operation of the machine the bell crank lever 15 is oscillated, through-the connections above described, from the cam groove Ben the disk 3 and thus the roll carriers 6 are actuated to tip the rolls. enable the extent of these tipping movements neeted to the vertical arm of t e bell crank 15 by means of an adjusting device'consisting of a block 18 mounted in a slot 19 in the vertical arm of the bell crank, this constructionbeing substantially the same as in the machine of applicants prior patent.

In the illustrated embodiment of the present invention a plurality of mechanisms are provided for actuating the adjusting device 18 and these mechanisms are arranged to actuatesaid device independently at different 1 times during the operation of the machine.

To enable the adjusting device to be acted upon by these mechanisms a bell crank 20 is pivbtally mounted inthe machine frame (How and at right angles to the bell crank 15 and one arm of this bell crank is connected by means of a link 21 to the'link 17, as best .shown in Fig. 2. l The other arm of the bell movement of the plate and guide the pin into the notch 24,. An upward movement of anyone of the plates 23 thus actual es the bell crank 20 and moves the adjusting device 18in the slot 19 of the bell crank 15. Each cam plate 23 is pivotally mounted at its lower end upon-one end of a bent lever'26. the other end of which is-provided with a roll or stud 27 arranged in the path of movement of a camsecured upon the cam shaft 4. The cams for actuating the bent levers 26 correspond in number to the cam plates 23 and are indicated on the drawings at 28, 29, 30 and 31. These cams are best illustrated in Figs. 3 and 4, and, as therein shown, are arranged to actuate the bent levers 26 and the cam plate 23 mounted thereon successively, and.

to cause but one plate 23 to be in engage ment with the pin 22 at a time. The plates 23 are guided in their vertical movements-by .means of links 32, a link 32 being provided for each. plate, and one end of the link being connected to the plate and the other end to a block 33 mounted in the front portion of the machine frame.

It will be evident that the extent of movement imparted to the bell crank 20 when a cam plate 23 is raised will depend upon the] angular position of the plate, and that the movement of the bell crank 20, and consequently the movement imparted to the adjusting device 18, can be nale in the machine 'frame and provided at its front end with a squared portion whereby the screw can be readlly turned by the operator by means of a handle or wrench to adjust the'block 33 and change the angular position of the cam plates 23 connected therewith.

It is necessary that each cam plate 23 after I having been raised into engagement with the pin 22 of the bell crank 20 shall be moved out of engagement with the pin before another cam plate is raised into engagement therewith. To insure this result a cam 36 is associated with each of the cams 28, 29, 30 and31,

and is arranged to en age the link 32 con nected to the cam -p ate which has been raised, as the cam which raised the plate passes out of'engagement with the con-e sponding bent lever 26.

The cams 28, 29, 30 and 31 are so arranged j that during the first portion of the revolution of the cam shaft 4 al of the cam -plates 23 remain in their lowest position out of engagement with the pin 22 of the bell crank 20, the adjusting device 18 at this time'being in the position indicated in'Fig. 2. While the adjusting device remains in this position the jack which is connected to. the jack oscillat mg mechanism moves inwardly and the relative lateral inclination of the roll and jack is determined solely by the shape of the cam groove 13 in the disk '3. \Vhile the inner edge'of the shank portion of the sole is being leveled the cam 28 is in engagement with its corresponding bent lever 26 and the position of the adjusting device 18 is controlled by the cam plate 23 which is actuated by the cam 28, sothat-the extent of the'la'teral inclination imparted to the roll is determined both by the shape of the cam groove 13 in the disk .3 and by the cam plate 23 which is in en g a ement with the pin 22. As the leveling r0 asses from the inner edge 01' the shank portion of the shoe on to'the inner edge of the 'forepart the. cam plate 23 which was in, engagement with the pin 22 is depressed and another cam plate 23 is raised into engagement with the pin 22 by the cam 29-and held in engagement therewith until the roll passes from the inner edge of the forepart onto the outer edge of the forepart. While theouter edge of the forepart is being operated upon 'the cam plate 22 which is actuated by the cam 30, is .in engagement with the pin 22, and while the outer edge of the shank portion of the shoe sole is being operated upon the cam plate 23 which is actuated by the clalm 31, is in engagement with the pin 22.. inclination imparted to the roll while acting upon-any one of the four portions of the shoe sole above referred to is thus controlled by the cam 13- and by one of the cam plates 23, and it will beevident that the amount of inclination imparted to the-roll while acting upon any one of these portions of the shoe sole can beadjusted by changing the angular position of one of the plates 23 without atectmg ftl e amount of mclination imparted to the re while acting upon .any of the other I portions of the shge sole. ustment But a single adrelative lateral inclination of the roll and jack for operation upon any ,one of a plurality of different portions of the shoe sole, andthe relaative lateral inclination of the roll and jack can be independently ad usted for operation upon any portion of the shoe sole.

The operation of all portions of the machine will be clearly understood from the foregoing description taken in connection with the description contained in applicants 'prior patent, and further description thereof is considered unnecessary.
